Welcome to the County of Riverside Vendor registration portal.  Completion of this process will allow your business to participate in future County business opportunities.  It also provides your ability to maintain your data as your business grows or changes.  There is a two-step process to register as a vendor; one for bidding opportunities and a second to set your company up to receive purchase orders and payment.  So, bear with us as we help open the window of opportunity for you.

The first step is to get set you up to receive electronic bid notifications.  The County utilizes the services of Public Purchase, a third-party electronic bidding software that allows vendors to register for specific goods and services they offer.  This would be done using NIGP (National Institution of Governmental Purchasing) codes as the commodity part number.  Once you are registered with Public Purchase, you will receive e-mail notifications of upcoming bidding opportunities for the items you signed up for.  You will also be able to view all the open bids, electronically respond to the bids and see bid results once they are awarded.  Additionally, you would receive notices of any addendums to those bids as well as have the opportunity to post questions and receive answers pertaining to that bid.  All questions and answers are posted on-line so that all bidders have access to the same information regarding the bid.

There is NO CHARGE to register and utilize this service for the County of Riverside.  Public Purchase has other services available for a fee, but that is solely at your discretion and not required to do business with the County of Riverside.

Just a couple helpful hints before starting your registration:

First, bid notifications are based on registered e-mail addresses.  Hence, it is recommend you use a generic e-mail address for your company, if you have one, and a second email address for a specific individual, if available.  That way, if personal e-mail addresses change, your organization still gets notification of opportunities.

Secondly, make sure your company has the user-name and password in a secure location, so that it is accessible when you are not available.

Before we forget, once you completed the Public Purchase registration, please return to this page for Step Two.

Now that you have successfully registered to receive bids, you need to complete step two.  If you are awarded the bid, you will need a contract or purchase order from the County, which will help you get paid for your goods and services.  In order to complete these transactions, you need to register in the County’s financial system.  Please click on the link below to register and complete the process.
